一喷施钾肥:在抓好葡萄合理施肥基础上,对叶面喷施钾肥具有增产、增甜效果。一般能增产7～10％,含糖量增加1.5～2.5％,方法是:在浆果迅速生长前施用0.4％硫酸钾或磷酸二氢钾或3％草木灰稀释液进行叶面喷洒。喷洒时,应以嫩叶和叶背为主,喷细喷匀,直至全部湿润为止,一般喷两次为好,在葡萄上不宜使用氯化钾。二喷施稀土:对葡萄叶面施稀土液,不仅增产效果显著,且含糖量增加0.6度。方法:在浆果变软期喷施0.05％硝酸稀土液。施用要求同上,
A spraying of potash: In grasping grapes rational fertilization, based on the foliar application of potash fertilizer with stimulation, sweetening effect. General increase in yield by 7-10% and increase in sugar content by 1.5-2.5% is achieved by spraying foliar sprays of 0.4% potassium or potassium dihydrogen phosphate or 3% ash, prior to rapid berry growth. Spraying should be based on young leaves and leaves, fine spray evenly until all wet so far, generally spray twice as good, should not be used in the grape chloride. Rare earth spraying II: Applying rare earth solution to grape leaves not only increases the yield significantly, but also increases the sugar content by 0.6 degree. Method: Spraying 0.05% nitric acid rare earth solution during the softening period of the berries. Application requirements Ibid,
